The model integrates the HEC-1 model, a 1-D dynamic channel-flow model, a 2-D non-inertia overland-flow model and the SWMM model to reflect the hydraulic processes in areas with different characteristics. The inundation of underground infrastructure during flood is also considered in the model. The typhoon Nari event in 2001, which resulted in severe flood in downtown Taipei, is simulated by the model. The result is compared with the survey records of flooded areas, which reveals the storage effect of underground infrastrucures is significant to the simulation results of highly developed urban areas. © IWA Publishing 2005.application/pdf383293 bytesapplication/pdfen-USInundation model; Underground infrastructure; Urban drainage basin[SDGs]SDG9Channel flow; Computer simulation; Floods; Hydraulics; Mathematical models; Underground structures; Urban planning; Flooded areas; Hydraulic processes; Underground infrastructure inundation; Urban drainage basins; Catchments; infrastructural development; runoff; urban drainage; article; catchment; flooding; geographic information system; mathematical model; river basin; short survey; Taiwan; urban area; water supply; water transport; water treatment; watershed managementjournal article2-s2.0-15744374003http://ntur.lib.ntu.edu.tw/bitstream/246246/176390/1/62.pdf
